The nuclide having maximum value of binding energy per nucleon is
Answer & explanation
Correct answer: option 3
The correct answer is Option (3) → ${ }_{26}^{56} Fe$
As we analyse the graph of Binding Energy per nucleus vs the Atomic Number.
One observe that the binding energy per nucleon increases until it reaches a peak at iron (Fe), which has an atomic number of 26. After this peak, the binding energy per nucleon starts to decrease.
